The Israeli military arrested overnight on Tuesday a Palestinian suspected of shooting dead two soldiers in the occupied West Bank in December.
Assam Barghouti is accused of shooting the soldiers at a bus stop near the Givat Assaf settlement in the Ramallah area on December 13, police said.
Israel's domestic security service, the Shin Bet, also accused him of involvement along with his brother in another shooting attack nearby, close to the Ofra settlement, that caused the death of a baby and wounded seven.
In the December 9 shooting, a pregnant woman was seriously wounded and her baby was born prematurely and later died.
Barghouti's brother, Salah, 29, was killed during an arrest raid on December 12.
Israel has arrested more than a 100 Palestinians in the manhunt for Barghouti.
Jewish settlers and their right-wing supporters had held angry demonstrations over the December attacks.
Assaf Barghouti was arrested at the home of an alleged accomplice in the West Bank village of Abu Shukheidim near Ramallah and was allegedly preparing more attacks, the Shin Bet said.
An AK-47 rifle, night-vision equipment and ammunition were seized during his arrest, according to the Shin Bet.
Prime Minister Benjamin Netanyahu welcomed the arrest and said that "the long arm of Israel will reach all those who harm our citizens."
